The authority now wants the owner of the rig, the Ocean Rig Company, to go through all safety routines before drilling can be resumed. On February 8, 6 cubic meters of so-called BOP-substances were dropped to sea, and on February 16, 4 cubic meters of drilling waste water ran into the sea after a technical disorder. Head of the Petroleum Safety Authority, Magne Ognedal, says the incidents do not pose a threat to ecology in the region, but that the pollution still is considered a serious violation of regulations, daily Dagens Naeringsliv reported.
